Synthwave sent me down the path of Vaporwave > Chillwave > Darkwave. There’s a not-unrelated genre called Mallsoft. Somehow that got me into Library Music. I found a lot of music on Bandcamp and archive.org. You can get downloads of full albums and discographies for a few dollars, name your price, or for free.

If you’re looking to do a deeper dive, the genre and sub genres are largely credited with being kicked off by Macintosh Plus - Floral Shoppe in 2011.

I listen to this stuff all day long while I’m working at home. My vaporware playlist is literally 7 days long (2350 songs). Here’s some of my picks.
